Alright well now that the case is out of the way I can move onto other matters.

So what is the best choice for coolant?
I wouldn't mind paying a little extra for non-conductive coolant, though I'm not sure which brand to go for. And how much more effective is distilled water than such coolants? If I did use water, I think I might use 7/16 tubing over 1/2 fittings just to make sure it's sealed.

After that I just need to figure out which mobo, so I'll pop over there now.
